我们调查了年轻人日常生活中3种健康行为（体力活动、睡眠质量和吃零食）的潜在压力缓冲效应。在2项密集的纵向研究中，在整个学年中进行了长达65天的评估，学生（研究1，N = 292;研究2，N = 304）报告了压力强度，睡眠质量，体力活动，零食以及积极和消极的影响。采用多水平回归分析对数据进行分析。压力与积极情绪呈负相关，压力与消极情绪呈正相关。一个人在特定的一天比平时更活跃，压力和积极情绪（研究1）和消极情绪（研究1和2）之间的联系就越弱。一个人前一天晚上的睡眠质量越好，压力和积极情绪（研究1和2）以及消极情绪（研究2）之间的联系就越弱。日常压力和积极或消极情绪之间的关联并没有因为每天吃零食而有所不同（研究1和2）。在紧张的日子里，增加体力活动或确保高质量的睡眠可能会缓冲压力对年轻人的影响。这些发现为健康促进和压力预防计划提供了潜在的目标，这可能有助于减少压力对年轻人的负面影响。
We investigated the potential stress-buffering effect of 3 health behaviors-physical activity, sleep quality, and snacking-on affect in the context of everyday life in young adults. In 2 intensive longitudinal studies with up to 65 assessment days over an entire academic year, students (Study 1, N = 292; Study 2, N = 304) reported stress intensity, sleep quality, physical activity, snacking, and positive and negative affect. Data were analyzed using multilevel regression analyses. Stress and positive affect were negatively associated; stress and negative affect were positively associated. The more physically active than usual a person was on a given day, the weaker the association between stress and positive affect (Study 1) and negative affect (Studies 1 and 2). The better than usual a person's sleep quality had been during the previous night, the weaker the association between stress and positive affect (Studies 1 and 2) and negative affect (Study 2). The association between daily stress and positive or negative affect did not differ as a function of daily snacking (Studies 1 and 2). On stressful days, increasing physical activity or ensuring high sleep quality may buffer adverse effects of stress on affect in young adults. These findings suggest potential targets for health-promotion and stress-prevention programs, which could help reduce the negative impact of stress in young adults.
